摘 要
逆向工程是當(dāng)前用于產(chǎn)品開發(fā)和仿制加工的一種先進手段，是集測量技術(shù)、CAD技術(shù)、激光技術(shù)、材料技術(shù)和計算機控制技術(shù)等為一體的高新技術(shù)，它針對現(xiàn)有的工件（樣品或模型），利用3D數(shù)字化測量儀器快速、準確的測得大量輪廓坐標點，并對這些坐標點進行去噪，匹配加以構(gòu)建，修改后輸入到CAD/CAM系統(tǒng)，生成NC的刀具加工路徑，或輸入CNC進行生成所需的模具，或者生成某種格式的文件輸入到快速成形機將樣品模型制造出來。三維光學(xué)測量機就是這樣一種設(shè)備，它可以將在三維物理空間中的被測物體復(fù)制到三維數(shù)據(jù)空間當(dāng)中并進行重現(xiàn)，我們稱之為建立三維模型。這種能力使三維掃描儀擁有非常巨大的應(yīng)用前景。由于逆向工程技術(shù)具有廣泛的應(yīng)用領(lǐng)域和實用價值，因此，世界上主要工業(yè)國家紛紛投入巨資對此項技術(shù)進行研發(fā)和推廣應(yīng)用，他們無不站在21世紀世界制造業(yè)全球競爭的戰(zhàn)略高度來對待這一技術(shù)。目前該項技術(shù)已經(jīng)廣泛應(yīng)用于機械零部件的快速開發(fā)、汽車和飛機覆蓋件的快速檢測和反求、快速模具、醫(yī)療及康復(fù)工程、家用電器、工業(yè)設(shè)計、工藝品制作以及兒童玩具等領(lǐng)域，取得了巨大的經(jīng)濟效益。本次設(shè)計主要是完成光學(xué)三維測量機機械部分和控制系統(tǒng)的設(shè)計，本文提出的結(jié)構(gòu)光三維測量系統(tǒng)是一種光柵式結(jié)構(gòu)光掃描雙目視覺測量技術(shù)。由于是面掃描，所以，在速度上有很大的優(yōu)勢，可以很好的實現(xiàn)被測自由曲面的快速、高精度的三維尺寸測量。通過對測量機的個部分部件的設(shè)計，最后完成光學(xué)三維測量機的設(shè)計工作。

Abstract
Reverse engineering is currently used for product development and imitation of an advanced means of processing, is set measurement technology, CAD technology, laser technology, materials technology and computer-controlled technology, which integrates high-tech, it addresses the existing part (or sample MODEL), using 3 D digital measuring instruments quickly and accurately measured the outline of a large number coordinates, and coordinates of these points denoising, match to build, the revised import to CAD / CAM system, generating the NC tool processing path, or enter CNC to generate the necessary die, or generate a certain format of the files into a rapid prototyping machine will be created by the sample model. Three-dimensional optical measuring machine is one such device, which can be three-dimensional physical space of the detected objects copied to the 3D data space and return them, we call it the establishment of three-dimensional model. This ability to 3-D scanner has a very great prospect. Since reverse engineering is a wide range of applications and practical value, the world's major industrial countries have invested heavily in research and development of the technology and application, they all stand in the 21st century global competition in world manufacturing strategy to deal with this highly A technology. Currently the technology has been widely used in the rapid development of machinery parts, automobile and aircraft coverage of the rapid detection and anti-seeking, rapid tooling, medical and rehabilitation engineering, home appliances, industrial design, craft making and children's toys, and other fields and achieved A huge economic benefits. The optical design is complete three-dimensional measuring machines and mechanical control system design, the paper's three-dimensional structure of optical measurement system is a grating structure of binocular vision measuring optical scanning technology. Since the scan, therefore, have great speed on the edge, you can achieve very good surface tested free of the fast, high-precision 3D measurement. By measuring machine parts parts of the design, the final completion of three-dimensional optical measuring machine design.
